Found these frame stampings on the M37 when I pressure washed it off for sand blasting. Ive never noticed them and dont think Ive seen pictures of like markings on other trucks. They are approx. below where the under bed tool box would be. They are also mirrored on the other side of the frame. Any ideas?
